(Cl. 2li- 12) 7 Claims.

This invention relates to a window frame.

It is an object of this invention to produce a new and useful window frame or casing provided with yieldable side elements which are adapted to loosely and frictionally engage the sash edges throughout the full length thereof.

It is also an object of this invention to produce new elemental features that can be removed readily whereby the weights used may become readily accessible.

It is also an object of this invention to produce a new assembly including the yieldable parts in such a manner so that the sashes will closely rit within the window frame.

It is further an object of this invention to produce a window casing from wood or plastic materials that may be worked in the carpenters trade and wherein all of the parts may be readily assembled and neatly iitted for its operation.

The features of novelty will be precisely and clearly set forth in the attached specication and drawings.

In the drawings:

Figure 1 is a side elevation shown foreshortened longitudinally for purposes of brevity and being partly in section;

Figure 2 is a bottom View of the device or casing including the arrangement of springs whereby the yieldable elements are attached to each other for yielding pressure upon the side edges of the sash;

Figure 3 is a transverse section showing the casing or frame including sashes as indicated on the line 3-3 of Figure 1;

Figure 4 is a fragmentary view in section taken on the line 4 4 of Figure 3, and also showing the parts broken away to disclose various elements of the assembly;

Figure 5 is an element which is adapted to be detachably connected to one of the yieldable elements of which it is a part;

Figure 6 is a perspective view of one of the riser elements forming a part of the combination of parts comprising the frame;

Figure 7 is a vertical section of the major portion of one side of the frame including the upper portion thereof and indicating how the operating parts are supported by the yieldable means which actuate one of the frictionally-engaging memybers in the frame;

Figure 8 is a transverse section taken on the line 8-8 of Figure 1;

Figure 9 is a perspective view of a portion of one of the yieldable elements;

Figure 10 is a perspective view of one of the companion yieldable elements;

Figure 1l is a perspective view of a central guiding strip located between the sashes and also between the yieldable elements; and

Figure 12 is a perspective View of a portion of an upright liller element and support.

Referring to the drawings, nishing strips 2 and 9 are secured on the outermost sides of the principal supports 3 and 1, by the usual means. The stool board Is is also secured in position by conventional means. Yieldable strips 4 and 4' are Inovably and yieldably located so that these strips may move toward or away from the sash at least one-eighth of an inch. To the left in Figure 3, the yieldable strips 4a and 4b are slidably and yieldably supported by vertical side pieces 3', 6', 6b and portions of the standard 'l'. Yieldably mounted strips ia and lib are frictionally held in position to engage the edges of the sashes sh.

In connection with Figure 7, it is noted that these yieldable strips are provided with spring sockets as indicated at the upper portion thereof, and at the central portion which sockets are each adapted to receive one end of a helical spring of the compression type. Spacer strip 8 in Figures '7 and 8 is also a support for helical springs as indicated at 8s, within the sockets formed therein are helical springs Ssp. These helical springs p are engaged in the sockets at the upper end portions of the yieldable elements 4 and 4' as indicated in Figure 8.

It is noted from Figure 1, that the intermediate portion of the frame is provided with a cross piece I2 which also forms a support for the end of a helical spring l2', as in Figure '7. The opposite end of the spring I2 is supported in the Socket of the yieldable element 4.

Attention is called tothe socket 5 located in element 4' of Figures 8 and 10. The block ll is provided with a tapered upper portion containing a slot Ils. Also the block Il is reduced on two sides to form a shoulder I4s and a depending leg i4 containing a groove I3 adapted to receive a wire loop l3a as shown in Figure 4. The block 3 I I is secured to the yieldable strip 4 through the medium of a pin Ilp which enters the slot Ils. Below the slot the block is secured to the element 4 by a screw I I f as also indicated in Figure 4.

In this connection it is to be observed that block II is detachably secured to yieldable strip 4 of which it forms a part.

Turning to the right side of Figure 3, it is noted that the spacer 3 is provided with a groove 3a which receives a tongue 4t located on the yieldable strip 4. The groove 3a is at least one-eighth of an inch wider than the tongue so that the strip 4 may yield a limited amount within the groove 3a. The strip E is rabbeted for more than half of itswidth as clearly indicated in Figure 11. tained in place by the sashes and also by the movable elements with which it is frictionally en. gaged. The rabbeted portion of strip 6 provides a stop to engage the strip 4, to prevent the said strip from extending too far between said vield-,l able strips 4 and 4.

In connection with Figures 1 and 2, it is noted 4', 4a and 4b, as clearly indicated in Figure 3.,

Portions I4, I4 and Illa an-d i417 are surrounded by a wire loop such as indicated at I3a, I3b of both Figures 1 and 2. Eachloop is provided with theshank I5, I', terminating in a hook I6, IB which are engaged respectively in rings on the endportions of tensioned helical springs I1 and I'I. It will be noted that the legs I4, I4', Ma and Mb, are yieldably connectedtogether and urged toward each other through the means ofthe ,loops and shank hooks and tensioned heli-.- cal spring I'I, Il.

In thisconnection it is, pointed out that the yieldable elementis connected toan, opposed. yieldable element on the other side of the frame and that there is direct cooperation between the opposed yieldable elements which engage respec` tively the associated sidesof the sashes.

In Figure 1 it is noted that each yieldable ele,. ment supports a pulley frame IIla anda pulley v I0, whereby the conventional cord and weight maybe used in coaction with the sashes.

In krFigure 9, the upper portionl of theyieldable element I is-disclosed as having a socket listo.. receive one end oi a helical compression spring., 8sp,,as indicated in Figure 8. The tongue listin.,v combination withy the groove 3a,.forms a stopfor theyieldable element 1I so that said element canonly have limitedxnovernent or' atleast one?,

eighth or" an inch.

InFgure 7 it is noted that the top .piec,e .'1` isI provided withl a groove Ich which loosely receives thefupper ends oi the yieldanle elements ii and-.4.

In.,orderto,remove the-yieldable.element. 4, it Thisris merely necessary to remove thesashesf. mayrbedone byremoving one oi the guides-5a ort-Gb. After the sashes `are removed or at leasti the front sash, `guide strips d are reinovedand. When this has been,

thebaci: sash also removed. accomplshedt is now merely. necessary tare--` move, the .fastening screwl I I f indicated in.r Figure 4,so,-,that.the. block` II may4 be ydisengaged from..

The strip 6 is frictionally and movably re.

the strip 4. Strip 4 may now be bodily removed from the frame including its pulley casing and pulley and rope as well as the Weight. A similar operation will permit the complete removal of the remainder of the yieldable elements.

In order to reassemble the removed parts a mere reversal of the removing and detaching operations is all that is required. Then the block Il having the slotted part IIs will again appear in the position indicated in Figure 4. The same identical operations will be performed with reference to the yieldable strip 4a and then the guide strips may be inserted in position just after the back sash has been placed. Since the strips 4 andx 4 are yieldable. they may be pressed toward eachother, but it `will benecessary to push them back to some extent While inserting the sash.

Even though the movable elements are inserted forlnovement, it must be noted that they can be tted so closely that no weather stripping will be necessary-inconnection with the Window frame of thisconstruction.

Though the materials used as indicated by the drawingsfare made of Wood, it is evident that most of the parts could be ymade of suitable plastic material.. andcould heavorhed in. thesame manner as .wood by the icarpenter.-

Inconnection. with Figuresl and 2, it isto be. observedthat thesill-I is provided with a pair., or supporting llerstrips Ib and 2b each being substantially'triangular or Wedge-shaped in outfv line. Theseller strips denne in .each instance oneright angular portion Irland each is pro, vided lin, its upper .inclined` portions with, notches Ie, 2e, 3e and 4e. These filler strips Ib. .and 2b. abut at( one ,end,., against the upright filler, post LI. and support said postsA in proper position withreflenence, to the sill. Theupper inclined` portion of each filler stripabuts againstthe sillI L and,,eaclri ,.ofvr these iiller., strpsfare secured .to.,the silLI bysuitable fastening means 4such asnailslor` screws, asindcated, atri c of Figure i.
